Comparative Cognitive Science of Intelligence

从比较认知科学的观点出发，我们研究了人类、黑猩猩、猕猴和鸽子认知功能的各个方面。黑猩猩的研究课题如下：使用视觉符号（如lexigram和Kanji字符）获得语言技能，数字记忆保持过程的概念，使用视觉搜索范式的视觉信息处理，使用遮挡物的统一感知，使用同时按压任务的交流研究，听觉和视觉刺激的跨模态匹配，两个辨别任务之间的选择行为，计算机引导的线条画除了这些在单一受试者测试情况下的实验之外，我们还开发了一种面对面的测试情况，即人类测试者直接与同一房间的黑猩猩受试者进行互动。主题是模仿动作和玩粘土。在第三个范式中，黑猩猩的智力是在户外环境中探索的。在一个10只黑猩猩组成的群落中，研究了工具使用和传播的出现。在竞争性喂养的情况下，社会互动也进行了研究。这项研究作为一个整体是与邀请到该研究所的外国研究人员合作进行的。研究小组还将成员派往国外，如荷兰的一群黑猩猩的研究和西非几内亚的实地工作。同样的研究也部分地在猕猴、猕猴、卷尾猴和鸽子身上得到了复制。所有的研究都放在一起，以说明智力的本质，并澄清进化趋势。

From the view point of Comparative cognitive science, we studied the evolution of intelligence examining various aspects of cognitive functions in humans, chimpanzees, macaques, and pigeons. The research topics in chimpanzees are as follows : Acquisition of linguistic skills using visual symbols such as lexigrams and Kanji characters, the concept of number memory retention process, visual information processing using a visual search paradigm, unity perception with occluders, the study of comunication using the task of simultaneous lever-pressing, crossmodal matching of auditory and visual stimuli, choice behavior between two discrimination tasks, computer-guided line drawing. In addition to these experiments in a single-subject test situation, we developed a face-to-face test situation where a human tester is directly interacting with the chimpanzee subject in a same room. The topics is the imitation of actions and the play with clay. In the third paradigm, the chimpanzee intelligence was explored in the outdoor setting. The emergence of tool use and the propagation was studied in the open-air compound where a group of 10 chimpanzee live as a community. Social interaction was also examined in a competitive feeding situation. The study as a whole was collaborated with the foreign researchers invited to the institute. The research team also sent the members to foreign countries, such as the research of a group of chimpanzees in Holland and the field work in Guinea in West Africa. The studies coming from the same idea is also partially replicated in a gibbon, macaques, capuchins and pigeons. All the studies were put together to illustrate the nature of intelligence and clarify the evolutionary trend.
